PT/INR Testing

PT/INR testing is used by many different medical professionals to get a general sense of how a patients blood clots and thins. The PT test is used to test clotting and may be helpful in explaining why bleeding occurs. The INR test is used to test the ability of blood to thin when under the influence of different medications. Because neither simple clotting or thinning is desirable in itself, finding a good balance of blood behavior is critical to developing treatment plans for any number of patients under different medications.
